Process Heat Solutions

Process heat solutions are engineered systems that deliver controlled thermal energy — as steam, hot oil, or flue gas — directly to an industrial process. They are used wherever a manufacturing process requires precise, reliable heat for cooking, drying, sterilising, dyeing, distilling, evaporating, or chemical reaction. ME Engineering designs, supplies, installs, and commissions process heating systems tailored to the temperature range, capacity, and safety requirements of each application. Our Process Heat Services Steam-Based Heating Systems

Steam is the most widely used process heat medium in Nepalese industry due to its high heat content, controllability, and safety. We design and install:

Shell-and-tube heat exchangers — transferring heat from steam to process fluid (water, juice, syrup, solvent) at pressures up to (confirm with owner) kg/cm² and temperatures up to (confirm with owner) °C Plate heat exchangers — compact units suited to hygienic food, beverage, and pharmaceutical duties Jacketed vessels and limpet coil systems — for batch heating of liquids in reactors, mixing vessels, and storage tanks Steam-to-air unit heaters — for space heating and drying tunnels

All steam heating equipment is sized to your process heat load (kW or kcal/hr), inlet steam pressure, and required outlet temperature. Thermal Oil (Hot Oil) Systems

Where process temperatures exceed 150 °C or where steam pressure would become impractical, thermal oil systems offer a safer and more energy-efficient alternative. Thermal oil heaters circulate a synthetic heat transfer fluid at temperatures up to (confirm with owner) °C at near-atmospheric pressure, eliminating the risks associated with high-pressure steam. We supply, install, and commission complete thermal oil systems including the heater, circulation pumps, expansion vessel, and distribution pipework. Direct Fired Process Heaters

For applications requiring very high temperatures or direct flame contact — such as certain chemical processes, bitumen heating, or fuel oil preheating — we supply and install direct fired tubular heaters and immersion burner systems running on diesel, furnace oil, or LPG. Waste Heat Recovery Units (WHRU)

Industrial furnaces, kilns, diesel generators, and boiler flue gases discharge large quantities of recoverable heat. We design and install waste heat recovery units — including economisers, recuperators, and heat recovery steam generators (HRSG) — that capture this energy and return it as hot water, steam, or preheated combustion air, directly reducing your fuel consumption and operating cost. Engineering Approach

Every process heat project begins with a heat load audit: we calculate the thermal duty (kW), required flow rates, temperature rise, and pressure drop before specifying equipment. This ensures the system delivers the required process temperature reliably without oversizing, which wastes capital and energy.
